I never had a chance to see the older 211 version but the 212 works very well. A friend of mine just put a set on and they seal very well on his P5 with 2 piece window and hard roof. The doors utilize a plastic piece with weather stripping that Velcro to the ROP. Then the doors attach onto a plate you rivet to the existing doors. This plate adds some rigidity to the door. If you do pickup a set, like the other Honda doors, work on fitment before completely riveting the plate in. The seal is great but the first door we put on rubs alittle on the back top corner, but I think the door bushing upgrade will fix this. We did better in the second door and it closes better. The only gap you have left is around the front and bottom of the existing doors but a little weather stripping could fix this. I was actually very impressed at how much an improvement they made to winter riding.
